treating packaged goods, and especially to a combined cookerand cooler. for use in canneries.- a."

5 In the preserving-jot. foodstuffs it isdeisirable to cool the heated can promptly,.as

soon as the cooking operation is completed.

'Inrthe past it has been "the practice to T conduct the heated cans-to' a .cooler by means 10 which permitted the material within the can to. continue cooking for anappreciable period after removal fromthe cooker; This is an; objectionable practice since it destroys the nice controlof the cookingtime which. is es v sential to high quality of produc't; Itis therefore one of the objects of .my invention toprovide for direct andrapid transmission. of the cans fromthe cooking to the cooling 1 of 'myi invention comprises aplurality of operation.

'20 Another object of the invention is the provision ofimproved means for removingth'e cans: from the cooking and cooling drums. It is a further object ofmy invention to provide a cooker and cooler mechanism which combines compactness with simplicity of [construction and which is peculiarly free of danger to the workmen because of the'im proved means of driving the moving parts:

Another object of the invention is the provision of'cooker and cooler drums into and I from which thecans are moved closely adj acent the tops so that relativelylarge' 'quantities of watermay be'retained in each-drum.

My invention-possesses other objects and features'of advantagef 'some ofiwhich', with I the foregoing, will be set forth in thefollowing description of my invention which isillustrated in the. drawings accompanyingv'and forming part of the specification. It is to be understood that I do notlimit myself to the within the scope of the claims.

Referring to the drawings: V Figure 1 a is a plan view of the apparatus, and Figure 2 is a side. elevation thereof.

:In termsof broad-inclusion the apparatus '1.

alined drums, in each of which carrier means It is also desirable to transfer the cans from;v

path connectin the side of oneof the drums "adjacent its end, tothe side of the-next drum adjacent the adjacent end. This necessitates 4 rections in adjacent drums; and in. the drivin'g, means provided for my'apparatus, I havelntroduced reversing :mechanlsm between the the carriers are" oppositely rotated. The inup inthe structure so that an abundance of water may be kept in the drums: This is. of

special importance in the cooling drum-in- S which it is desired to maintain as large a; "bodyofcold water as possible in order to [more efiectivelyabsorb the heat'from the hot cans; Improved means are also provided for extracting the cansfrom the carrier means.

This shaft extends the full'length o1 the cooker and is connected by means of the gears 27 with the transversely extending shaft 28 which drives the sprocket 29 of the elevator: 31, thru a snring held clutch 32 of known construction. 'In] accordance with well-known practice the elevator 31 receives the cans and raises them to the runway 33 over which the cans roll i'nt o'thecoolterdl uifir" Fixed on thcshaft 18 intermediate its end is a worm 34 inmesh with a worm wheel 35,

-lhis' reversal of the direction of movement=ofthecarrier framesin the two drums is a very important partoff my invention sincev it permitsme to eflect a very rapid transfer of the cansemerging from the cooker I to'tli, cooler and at the same time, keep the cans moving, on leaving and entering the drumsvin the same direction as th car'riers- Theentra'nce passage 51 of the cooler drum" cooker' drum and on the same side offthe group of drums as the discharge passage 52 of thecooker. Thesepassages 51and 52, like is thereforeplaced atthe end adjacent the the-inlet passage 53 of the cooker andthe discharge passage 54 of the cooler are "ar ranged tangentially so that the cans move prising the curved end sections 56 and 57,

the openings. r V

The curved sections '56 and 57 "comprise lit" the cookerdischarge' passage with the cooler inlet passage is a trackwa'y or passage conilif to givethe shortest possible passage between 7 trough-like members in which a track 59 1s arranged on theb'ottom, so that the cans readily roll around the curve. on the ends of the curved section permit ready connection with similar flanges on the castings enclosingt-he outlet and inlet passages. The straight section of the assage Way'58 is composed of angle bars eras shown Flanges 60 in I*ig ;ure Hover which a; retaining rail 62 is held by the bracketsosy In or'der to utilize gravity'ih iiecting' the transfer of the cans from one drum'td the next I prefer tocsomewh'at elevate the cooker .above the coolerd'rum' as indicated in Figj ure 2 so that the passage or trackwayis incline'd and the cans roll readily from i the I othenmw ,c V a a2.; Inan apparatusg'fortreating packaged F r goods, a pair-of drums, rotary carrier means forPconviaying the packages thru'jthe drums, unitary ineansfor rotating saidcarrier means, I Y in opposite directions, and a passage lying on cookerdrum into {the cooler drum. H 4

Means are provided for extracting the cans on therotary carrier frames from the cooker and cooler drums. As shoWninFigures l and 4c, the extracting means comprise a pair of transfer'or pick-up-arms;64, having the fianges'o by whichthey are con veniently fixedv in place. The "arms are spaced apart a distance shorter than the length of the cans, and project from they mouth of thepassage,.in which they are located preferably tangentially toward the carrier frame. The ends of thetransfer arms are beveled on theunder side so as to eliminate any step at the'end and facilitate the rolling of thecans upon them as they In order to permit the arms to be' positioned are carried around on the carrier frame.

7 close to the can-supporting surface of the carrier. frame, the radial flanges 'ofthe angle bars on the frame are'provided with notches the arms. a

Since each can is pushed across these 66 of width suficient to-' clear the ends of notches on its lasttrip around the drum, "means are provided for preventing the seamed edge a of the can from jamming against the edge of the notches.- This struc ture is illustrated in both Figuresr'l and 7.; A When the notches 66 are formed, the edge 69 toward which the cans move is bentdownwardly a small amount, so that the seamed edge of the cans, instead of striking ashoulder edge, rides up on the supportingis'urface without injury or jamming. a

For purposes of the presentv description I have shown but two drums, but obvlously the series may be extended to include a number of drums more than two. features of my invention are also applicable to other arrangements of the severaldrums as well as to the seriesshown, but in every case I desire to: facilitate a direct transfer of cans in thedirection of the travel of the carriers, at the respective points of discharge and intake bymeans of a direct passage be tween adjacent sides of the drum; that is,

by a passage which does not cross over from one side to the other of the series. a I

By the arrangement shown, one end of the cooker drum is leftfree for control devices c and temperature and pressure indicating instruments, and a minimum amount of floor space'is occupled.
